Modern geological and planetary data contradict to hypothesis of cold homogenous of the Earth and shown it hot heterogeneous origin. This genesis allows convincingly to decide discussion genetic problems. The core was formed before the mantle as a result of magnetic force influence. Big power magnetic forces caused big impact heat of the core and origin of convection in the mantle. Rise of impact heat the mantle during accretion caused origin of opposite thermal gradient and absence of convection during Precambrian. Convection was formed in Proterozoic as a result of heating the mantle by the core. Rise of the mantle substance, heated by the core, resulted in big superplumes, oceans, subduction and collision areas. Rise of crystallized melts of the synaccretion magma ocean resulted in plumes and basic magmas. Crystallization of acid layer of the magma ocean resulted in crystalline crust and Precambrian complexes. Rise of residual melts from different layers of magma ocean caused evolution of magmas of ancient platform from acid to carbonatite and kimberlite. Magmas of ocean, subduction and collision areas are the result of friction and decompression melting of the magma ocean differentiates.
